HPE J4860D 1 Gb SFP LC LH 70 km Single Mode Fiber Transceiver module

HPE J4860D 1 Gb SFP LC LH 70 km Single Mode Fiber Transceiver

Overview

The HPE J4860D is a 1 Gigabit small-form-factor pluggable (SFP) transceiver module designed for long-reach single-mode fiber links. It supports the 1000BASE-LX/ZX class of specifications and uses a duplex LC connector over single-mode fiber (SMF) to achieve link distances up to 70 km (some compatible third-party claim up to 80 km) at 1550 nm wavelength. It’s suited for enterprise access and aggregation switches in campus or metro networks where 1 Gb/s ports need to connect across dark or lit fiber spans without deploying 10 Gb/s.In real-world use you’ll plug it into a compatible SFP slot — often in an HPE/Aruba switch or router — and pair with an LC-LC single-mode cable to another SFP. Because it’s designed for long-reach light levels, it’s typically used in backbone links, fiber runs between buildings or sites, or where conventional multimode fiber isn’t feasible. Ensure your switch or network device supports LC LH modules and verify vendor compatibility — some devices require specific vendor-coded SFPs.

Key Features

• Supports 1 Gb/s data rate (1000BASE-LX/ZX) over single-mode fiber for spans up to ~70 km.

• Duplex LC connector, making it easy to install in standard SFP ports and use LC-LC patch cables.

• Single-mode fiber (SMF) optimized for long-reach links between buildings or across campus infrastructure.

• Low power consumption and hot-pluggable SFP design, so you can replace or upgrade without powering down the switch.

• Digital Optical Monitoring (DOM) capable in many cases — allows real-time monitoring of transmit power, receive power, temperature, etc.
